Answer;
<u>= 56.96 mA</u>
Explanation;
From the Ohm's law;
V = IR, where V is the potential difference in volts, I is the electric current in amperes and R is the resistance in ohms.
V = 4.5 volts, R = 79 Ω
Making I the subject of the formula we get;
I =V/R
= 4.5 /79
= 0.05696 A
But, 1 A = 1000 mA
Thus; 0.05696 × 1000
<u>= 56.96 mA</u>
Try calculating maybe that would help you
A battery is a device that stores chemical energy and converts it to electrical energy. Two terminals made of different chemicals (typically metals), the anode and the cathode; and the electrolyte, which separates these terminals.
Hope I get it and hope this helps

Answer:
Mars and Earth are two of the planets of the solar system. Some of the ways in which Mars is different from Earth are as follows-
- The size of the earth is bigger than Mars as Earth has a radius of nearly 6400 km, whereas Mars has a radius of about 3400 km.
- The atmosphere of earth is primarily comprised of gases such as 78% of Nitrogen (N₂), 21% of Oxygen (O₂), 0.03% of Carbon dioxide (CO₂), and 0.9% of Argon (Ar), whereas the atmosphere of Mars is mainly comprised of 95% of CO₂, 3% of molecular N₂, and 2% of Ar.
- The surface gravity also marks a contrasting difference as on Mars, the gravity at the surface is only about 38%, in comparison to the gravity at the earth's surface.
